I was up at the lake of the woods fishing for last day and a half, I have Minnkota
ulterra 112 36 volt. both days I was spot locked in some pretty good wave action, this was my first trip with the new trolling motor and battery, so I kept a close eye on My battery charge and was amazed, at the end of the trip the battery was still had 76% charge. first day spot locked from 1pm to 7pm and second day from 8 am to 8;30 pm, the wave action averaged 2 to three feet wind was 17 to 25 MPH. I had the charger with but never had to use it.
Pretty funny while walking back from the fish cleaning shack the number of boats that had power cords running to them, but not mine one less thing to put away before starting your day. Oh, and by the way when the battery came it wasn't charged it took less than three hours to charge it, I also purchased the charger as well plugged it in the red light came on and when the battery was the charge the green light came on and the charger shut off on its own, I unplugged it and was good to go. Oh, by the way thanks fast order fulfillment, less than a week from Florida to Minnesota with standard shipping.
I use the Abyss 36V 105AH battery with a Rhodan 120 lb thrust trolling motor. This charger is permanently installed on my Key West 244 CC and keeps the battery at tip top shape. If you are buying an Abyss battery, this is the charger to use. It just works and is build very solid. I do not use engine power to recharge, only this charger. It gets a workout and is blistering fast at recharges.
Although it took a while to get my new battery and charger, the performance has been amazing with a 36v Motorguide Xi5 electric motor! 105 AH battery with 4 x 5 hour trips trolling for walleye at 1.5 MPH still at 37% SOC! Love the Bluetooth data on my phone to monitor battery performance.
